lle known that l., Hornos H. BUnDnrr, s citizen of the United States, and a resident ci?` li-opedale, in the county of lll/forcestcr and Siate of ll/lessachusetts,l have invent ed an Improvement in Builder Mechanisms, ci which the following description, in connection with the. accompanying drawings, is

specification, lille characters on the drewings representing like petits.

This invention relates to builder mechenisms :lor 'yarn if; ling or spinning machinos, and nio, ,seoicularly to such mechunisnis provided vs'ith s. bunch building nttnolnnent.

in that type of looms known es feeler looms, it is non1 'the common practice to wind lillinp; carriers or 'bobbins for use in such looms by providing c few preliminary' windings upon thc'lilling carriers or bobbins, technically known as e "minch and upon the completion of such preliminary winds or bunch lo pass to regular service winding-rs, and various types of mechanisms have been devised for this purpose. One of the ojects" of the present invention is to provide n builder mechanism with a bunch builder attachment of simple and novel character, which readily applicable to ik C builder mechanisms now in common useu As ordinarily practiced, the yarn guide, or ring raill it muy be, is depressed on the completion of c series kof wound bobbins to permit 'the full bobbins to be dol'ed, and

such yarn guides or ring rail are usually held in such lowered position by some sort 01 u catch or trip.

1When a series ci filled `bobbins have been replaced by empty bobbinsvor illing carriers und a bunch is to be placed upon the lilling carriers or bobbins, it is desirable that the bunch building nicchmiism may `he placed in operative position to wind the bunch when the machine is again started, :md one of the purposes voli the presentinvention is to provide e bunch building attachment which will enable the machine attendant to place. the bunch building mechanism in operative relation before starting the machine to wind a fresh set of bobbins, and which will thereafter and von completion of' the bunch automatically pase to regular traverse Y which will continue to the end of the wind* ing operation. i

In' accordance with the present invention, the bunch buildingfottachment comprises e worm lu'ivingspirell threads, Aand which is mounted upon the builder arm 'for movementv transversely thereto and is normally quiescent during regular windings, sind in addition thereto the invention provides a rotating device for engagement .with the Vthreads of the worm to progressively move vthe-worm from operative relation with seid `device on 'the completion` of the bunch, to

thereby permit continuation of the windings by regular traverse. To move the bunch. builder mechanism into operative relction to build the bunch, the Worm on the builder larmis manually controlled to movev it into bunch building position prior to the commencement of the windings ofthe new setoi:

`loobbins, and the direct engagement of the rotating bunch' building device with v.the worm threads serves to maintain the Worm in bunch building relation with Said device and to be automatically rotated thereby to move the Worm into its inoperative position.

' The` invention, novel features thereof and new combination of parte will best be mode clear from the following description end the accompanying drzrsvingsk of one good practical form of the invention, "which in. its true scope will be definitely set forth in jthc claims. A if.'

In the drawings: 4 L Fig. 1 is a perspective view of c winding machine and builder mechanism containing the present invention;

3--3 of" Fig. 2 but shoving the reloti'on of".

'parts during iegular trave The advantages of the present invention-ly Fig. 1 it may comprise theiisual frame 1 having the spindle rail 2 on which the spinv s ft 21 driven, as usual, from dles 3 are mounted for rotative movement.- Above the spindle rail2 is shown the usual ring rail 4,1iaving the yarn guides orrings and travelers 5 for directing the yarn to the bobbins'during the traverse of the ring rail.

Mounted in suitable brackets 6 extending from the cross-tie 7'is the rock shaft 8 having'an arm 9 on which rests the rods 10 connected to the rin rail and normally tending tobe ,raised y the counter-weight 11. as usual. The rock shaft 8 has the segment -arm112to which may be connected the ilexible connection or. chain 13 which passes over the guide pulley 14 'and has it's lower end portion secured'to the let-'back drum 15 mounted on the builder arm 16. The builder arm 16 is pivotally mounted upon the machine frame as at 17 and has a rearwardl extending arm on which is suprte a weight 18. The' builder arm 16 as a follower 19 which during the main traverse windings rests upon the periphery of .the main builder cam 20` which may be a propriately supported on the rotative some going part of the machine. These parts may be of usual construction.

Mounted upon the builder arm is the usuall pick shaft 22 to which yis wheel 23 by which the pick shaft is stepped alon or rotated, as usual in this Atype of buil er mechanism, during the. rising and falling movement ofthe builder arin under the actuation` of the main builder cam. ,Sccured to the pick shaft 22 is a worin 24 which engages a toothed wheel 25 to which the let-back drum 15 is secured, so that 'during the main service windings the ring rail will `be progressively raised to lay the inain service windings lin usual manner. `All the parts so far described may be of usual con'- struction and need no further elucidation, since they are well'known in the art.

The builder Vaiin 16 as shownhas able secured thereto by vsecured the pick adjustthe bolts 26' a bracket 27, and adjusting screws v2S foi-in a convenient means for adjusting the bracket relative to the builder `arm 'when the bolts ose. A sind ordena sima sop is adjuseibiy mounted in the lower portion 29 of the bracket' 27 "by threaded connection therewith, as shown in' Fig. 3, v.and is provided which vengages t D :worm is moved outwardly from the builder of the rotating -when the machine is started with the bunch with a`check. nut 31 for hldingthe `stud in adjusted position. The stud 1s enlarged at its outer portion to form a stop shoulder 30*` and mounted for sliding movement on the enlarged'` outer portion. of the stud 30 is a worin 32 having a sleeve or hub 'portion 33, the inwardl extending edge 33 of he shoulder 30* when the arm into bunch building position.

Mounted for rotative movement is a bunch building `device 34 which is shown in the present instance as mounted upon the cam shaft21 and may be conveniently secured thereto for rotative movement therewith by means of the bolts 35, the construction being such that when the builder arm lis lowci'ed by the machine attendant, lie may move the worm in a direction transverselyl of' the builder arm by manual effort into position below the rotating bunch builder device 34, `which will thereupon engage the threads of the worm and maintain the parts in operative relation to progressively move the worm transversely of the builder arm out of operative relation when the bunch has been completed, whereupon regular service traverse ensues. Tlie rotating bunch building device 34 is herein shown as of the general disk form, but the invention is not necessarily limited in this respect, and if desired its periphery may be varied in foriin `In order, however, to properly retain the worin 32 and rotating bunch building device 34 in operative relation when they are directly 'engaged to build the hunch, the edge portion 36 is vformed to register with the threads of the worin, the construction bein such that upon rotation unch building device.34

building mechanism in bunch building position, the edge, portion 36 of the rotating device 34 will enga'ge the spiral groolves in the worin and rotate the latter in a; direction to progressivel niove the worin backward or out of bunci building relation with the bunch building device.

During man service windings it is desirable that the bunch building worin shall re- 'in-ain quiescent, and since it may contact with vthe side of the rotating device. 34, which is herein shown as rotating with'the niaiii builder cani, ineans are provided to prevent rotative inovenientfof the lworin during regular A ti-averse. Such means. consists o? a pin 37, iii the'pi'csent instance, which extends i'i'oin the outer-tace portion 38 of the woini and bears u'ponthe peripheral portion of thev bunch building device 34 during main service windings, the result being .that on coinii'ienceinent of the vbunch building-windings of a new Vsetof bobbins, the worin; 32 f will engage the rotating device 34 in' silh- 'stantially the same place as the previous iufm fi braxcimi; Iii? im Mmmm giri wm, faam@ pari-milan@ imiiciing Wmrm.
